  1. \({n}_{0}\)—the ratio of the number of pore voxels to the number of all voxels from CT scanning.
  2. \({n}_{m1}\)—the ratio of total pore volume (cm3) to the bulk sample volume (cm3) of the small size sample from MIP test.
  3. \({n}_{m2}\)—the ratio of total pore volume (cm3) to the bulk sample volume (cm3) of the large size sample from MIP test.
